Overview

Use it to contextualize unusual price, reserve, or reliability conditions.

Query contract

Use FINAL or argMax over ingested_at for each event_time and exact message.

Analysis rules

  • Group only after preserving the declared grain: event_time, message.

Interpretation

  • An operator event can corroborate system conditions but does not identify the marginal unit or allocate a zonal congestion component without companion market evidence.

Access

Query from your own tools

Use the guarded HTTP endpoint directly, or connect an MCP client and load the dataset contract with describe_data before calling query_data.
